Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed m 2a, 1903. Serial n. 159,174.

To all whom it may concern.-

Be it known that I, SrooKToN BORTON, of Providence, Rhode Island, have invented a new and useful Im" rovement in Seams, which invention is fu ly set forth in the following specification.

My invention is an improved seam partic- "such edges by flat seams, such as heretofore commonly used, and particularly those made by a single operation, reat difficulty has been experienced in the e 'ort to-confine, hold down, cover, or secure all of the thread ends, the object being to prevent them from sticking up, and thereby detracting from the smoothness and appearance of the finished seam. A very few threadends projecting at intervals will seriously mar the appearance of an entire seam.

My present object is to provide -a seam which will overcome these difficulties, possessing also other advantages as to strength, ap earance, and durability.

n the accompanying drawings .1 have illustrated several forms of my impro;ed seam."

Figures 1 and 6 represent the appearance of the several seamspn one side (for purposes of description designated the upper side) of the goods. Figs. 2, 3, 4, and 5 represent the appearance of the several seams, respectively, on the other side (for purposes of de scrigtion designated the under side of the goo s.

In the drawings, 1 and 2 are two pieces of fabric or portions of a single piece of fabricsuch, for example, as cut knit oods-the o posing orabutting edges of which are broug t together along'l'ine-3, which is the line of division or separation between the opposing edges.

4, 5,-6, and 7 arp four parallel or ap roximately parallel rows of stitches, stitc es 4 and 5 being formed in the fabric 1 on one side of the linelyand stitches 6 and 7 in fabric 2 on the other side of said line,

Knit goods when out ;Chain-stit,ches are shown in the drawings appearing on the upper side of the goods,

Figs. 1 and 6, as a succession of loops, each assing upwardly through its next preceding 00p and on the under side of the goods, Figs. 2 to '5, as a single thread assing from one heedle-hole to the next ut any suitable form of stitch may be used,as, for example, the ordinarylock-stitch or the Grover and Baker stitch,

' Referring to Fi 1, 8is a cross-thread passing alternately om one outside line of stitches (4 or 7 to the other outside line of stitches, (7 or 4.) It passes under the loops of each stitch of all four approximately arallel lines of stitching,'as well as aroun every other loop of the two outside-lines (4 and 7) at the point where said loop emerges from the fabr1c. In Fig. 6 the cross-thread 8 runs back and forth from one outside line of stitches to the other in the same manner, but is drawn sufliciently ti ht to pull the interlaced ends of the loops rst at one edge of the seam and then at the other over toward the center of the seam, as at 9 9, for example,

giving the seam a zigzag appearance.

Referring to Fig. 2, 10 is a cross-thread on the under side of the goods passing alternately from one outside'line of stitches (4 or 7) to the other and under each stitch of all four lines of stitching, as clearly shown. The preferred dis osition of thread 10 with relation to threa 7 on the other side of the fabric is shown by the dotted-line illustration of thread 10 in Fig. 1.

In Fig. 3, showing the appearanceon the under side of the goods of another form of the seam, 11 and 12 are two cross-threads, each passing alternately, but in an op osite direction to the other from one inside ine of stitches (5 or 6) to the other inside line of stitches. Both cross-threads pass under each stitch of the two inside lines of stitches and cross each other at the line (3) of the two abutting edges of the fabric.

In another form shown in Fig. 4'the seam on the under side of the goods is the same as in Fig. 3, except that one of the two crossthreads 15 instead of passing from one inside line of stitchesto the other passes back and forth between'the outside lines of stitches 4 I and 7, assing under all of thestitches of each of the our lines of stitching, as clearly shown. 1

rection to the other, from one outside line ofv stitching (4 or 7) to the other, said threads :18

- and 1-9 passing under cross-threads Hand :17 i and crossing each other at about the line of th abutting edges of the fabric. Each thread 18 and 19 passes under each stitch of 1131 four lines of stitching.

In in improved scam the two inside lines of elite ing may be placed ve near to the e es of the goods to be joine d there being litt eif any transverse strain or pull thereon.

They serve principall to secure and hold 20 down the cross-three s as well as to catch and securely hold down thread ends which may project from the edges of the fabric. The outside lines of stitching are located fartheiback from the edges, where there is no danger of their ulling out through and tearing the edgeso the goods when subjected to strain or ull in a transverse direction. They are there ore m'adgto serve principall' to re sist'any transverse ull or strain ten ing to separateth'ejoin'ede 'g'es. 'The-cross-threads on both sides of'thegoods-also serve to catch and secure or hold "down projecting thread I ends, as well as to hold the two edges together and resist any transverse strain or till tending to separate the same; but this tter' function is served principally by the 'c'ro'ss thread, or threads which pass from one i to the other, either. In the j .preierred form of my seam, therefore, I em-" outside line of stitching. on one or both sides 0 the goods.

ploy a cross-thread or cross-threads on one or both sides of the code extending between outsidc lines 1o stitching. More than four lines of stitches may, if desired, be used.

be apparent, my invention is capa bio of many embodiments other thanth'ose particularly shown and described.

used, a corresponding number of needles will be employed. For example, .a seam comprising-four lines of stitches within my inven '-tionmay also have a fifth line of stitches formed between the two pieces of fabric along the line 3, Fig. 1.

another aim shown an Furhemorje, while my improved seam is parted for joining together twoj 1. ln' a seam,'the combination with fabric, of four -approximately .parallel lines of stitches, two 'cro'ss threads on 'o'ne'side ofthe tabrie one oonneetingthe outside .of

stitches and other, the inside of stitches, and a cross-tln ead .conneoting two rlfthe lines of stitches on the other side of the fabric. Y

"2. In a scam, the combination-with-iabric, of four a proximately parallel lines of stitches, an two crossthreads one connecting'the outside line of stitches on each side of the fabric, and a cross-thread "connecting the inside lines 'of stitches on one-side bf'fthe fabric.

3. In a scam, the combination with two opposing edges of fabric, of four approx mately parallel lines of stitches passing through the fabric two on each side oi the line 0 division, a cross-thread connectiggthc outside lines of stitches on'one side -the fabric "and a cross-thread on the other side of,

the fabric connecting the two lines dfs'titches on op osit'e sides of the line of -abutment.

4. i n a scam, the combination with two opposing edges of fabric, of four approxh ma'tely parallel lines of stitches passing t'hrou h the fabric two on each side of the line 0 division, a cross-thread on one side oql the fabric connecting the outside lines bf stitches and passing under the inside linesbf stitches, and a cross-thread on the other side I of the fabric connectin two lines 'ofs'tiftche's 'on'op osi'te sides of the ins of abutment.

5. n a scam, the combination with "two opposing edges of fabric of four approximately parallel lines 'o stitches passing through the fabric two on each side of the line of division, and two cross-threads one IOC on each side of the fabric connectin' the out side lines of stitches and passing un' er the mside lines of' stitc'hes'.

6. In a scam, the combination with two opposing edges of fabric of four approximately parallel lines o stitches passing throu h the fabric two on each side of the line 0i division, a cross-thread on one side of the fabric connecting the outside lines of stitches'and passing under "each stitch of all four lines of stitches, and a cross-thread on the other side of the fabric connecting two lines of stitches on opposite sides off/he line of abutmen a 7. In a seam, the combination with'twoopposing ed es of fabric, of four approximately paral through the fabrictwo on each side of the line of division, and two cross-threads one on each side of the fabric connecting the outside lines of stitches and passing under each stitch of all four lines of stitches.

,8. In a scam, the combination with two opposing edges of fabric, of four approximately parallel lines of stitches passing el lines of stitches and passing throu h the fabric two on each side'of the line of division, and a cross-thread connecting the outside lines of stitches on one side of the fabric and drawing the same in toward the inside lines of stitches at the points where it passes around said outside lines of stitches.

9. In a seam, the combination with two opposing edges of fabric, of four approximately parallel lines of stitches passing throu h the fabric two on each side of the line 0 division, and a cross-thread on one side of the fabric passing under the inside lines of stitches and connecting the outside lines of stitches and drawing the same in toward the inside lines of stitches at the points where it passes around said outside lilies of stitches.

10.- In a seam, the combination with two opposing edges of fabric, of four approximately parallel lines of stitches passing throu h the fabric two on each side of the line oi division, a eross thread on one side of the ic passing under the inside lines of opposing edges of fabric, of four approximately parallel I lines of stitches passing through the fabric two on each side of the line of division, and a cross-thread connecting the outside lines of stitches and passing under the inside lines of stitches on one side of the fabric.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses STOCKTON I BORTON.
